Learning efficacy according to AAR perspective and line of fire feature. DISCUSSION In the present study, we investigated the influence of AAR features in VR on learning efficacy of police officers. We defined learning efficacy as the trainees’ level of confidence in the application of their acquired knowledge and skills in real-life situations (Srivastava et al., 2019). To examine the influence of AAR features on learning efficacy, we investigated two hypotheses: first, we examined whether using the AAR perspective from a suspect view enhances learning efficacy more than other perspectives such as a review from the police officer perspective or from the bird’s eye view only. Second, we hypothesized that turning on the line of fire of the weapon of the police officers during the AAR would enhance learning efficacy compared to not using this feature during the AAR. Both hypotheses rely on the premise that they provide
